Weather mismatch
Why Pokémon GO Weather Does Not Match Real Weather
Many players notice that Pokémon GO weather does not always match the weather outside. The game may show Windy while your weather app says Cloudy, or it may keep Rainy weather after rain has stopped. This is normal and it is one of the reasons weather boost prediction is difficult.
Pokémon GO likely uses forecast data
The game appears to rely on forecast-style information rather than instant local observations. Forecasts are generated before the weather happens, and real conditions can change afterward. If the forecast expected wind, rain or clouds, the game may still display that condition during the relevant hour.
Hourly blocks can create delays
Pokémon GO weather usually changes in blocks, not every minute. A weather icon can remain active for a while even if real conditions already shifted. This is especially noticeable during fast-changing weather.
Windy is one of the hardest categories
Windy weather is difficult because wind speed can vary between forecast models and local measurements. A forecast may predict a short wind window that is enough for the game, while the real wind later feels weak. That is why PogoWeather checks wind windows instead of only a single instant value.
Cloudy and Partly Cloudy are also tricky
Cloud cover thresholds are not universal. One provider can report 85% cloud cover while another display still looks like Partly Cloudy. Pokémon GO has its own thresholds, so PogoWeather combines weather codes, cloud cover and calibration from observations.
How to use estimates correctly
The best approach is to treat PogoWeather as a ranking tool. It helps you find cities that are more likely to show the target weather, but the final check should always be done in-game. Reporting mismatches helps improve the model over time.
